Abstract

The aim of this project is to develop a three-dimensional computer input device which provides a better interface between a user and their computer. The user wears a ring on his or her finger which transmits an ultrasonic signal to a receiver array. A microcontroller then calculates the three-dimensional coordinates using time-difference-of-arrival methods. These coordinates are input to the computer as a standard human interface device (HID) USB peripheral. X and Y dimensions control the mouse cursor on the screen, and the Z dimension can be used in three-dimensional applications.
